Transceiver Standard/Enhanced PCS on Arria 10 GX (Dev. Kit DK-DEV-10AX115S-A)

Hi,

i have some problems with test about transceiver on Arria10 GX.

My goal is: check transceiver comunication with different speed.

I have already done a test a 5Gbps with Native PHY with indipendent Tx and RX block with Standard PCS (10bit) and Bitslip. The test was successful.

Now i want to test the comunication at 10Gbps using Enhanced PCS (64bit) and Bitslip. The parallel receved are wrong, but the bitslip shift the word by 1 bit every rising edge. The receved word is wrong, because have more '1' than i send by TX.

it seems that an internal coding is applied to the block, but every block aren't enabled.

My option are:

PCS-PMA interface 64

FPGA fabric interface 64

RX

FIFO mode phase compensation

FIFO partially full threshold :23

FIFO partially empty threshold: 2

Enable Rx data bitslip

Eenable rx_bitslip port

TX:

FIFO mode phase compensation

FIFO partially full threshold:11

FIFO partially empty threshold:2

Any advice?

Thanks,

Marco
